What is a wing walker used for?

A wing walker is specifically designated to ensure clearance and safety while an aircraft is backing up. This role is crucial on an airport tarmac where there are numerous obstacles, other aircraft, and personnel in close proximity. The wing walker's primary responsibility is to signal to the pilot or vehicle operator when it is safe to proceed, helping to prevent collisions or accidents.

In aviation operations, clear communication and safety measures are essential, and the wing walker acts as the eyes and ears on the ground, keeping a lookout for any potential hazards that may not be visible to the pilot. This position is particularly important because aircraft have large wingspans and blind spots, making it easy for collisions to occur without vigilant oversight.
